Does anyone know who makes the Instrument Panel Cluster for the Sunfire's ?

Rganks...

more than likely delco y?



My car may run 18s, but I can do your taxes in 10 seconds flat.
JBO lube - they would never have enough in stock and we'd never see RodimusPrime again

Want to get a module to feed a signal to the stock Tach so it works without getting it from the PCM.

i doubt its possible.



car audio noob since 1984.

It's possible, but it is one hell of a project. The tach signal is part of the serial data from the ECM. It goes through a demultiplexer, which breaks out the various signals, then each signal goes through an IC that converts the signal into a 2 part regulated voltage to the needle motors. All of this happens on the printed circuit board, so if you want to modify it, you'd have to remove one of the components linking the tach motor to the serial data, then wire your own logic circuit to convert the pulse from the ICM into the regulated voltages.

The only other option is if you can find an aftermarket tach that has small enough components to use for the factory needle. You'd most likely have to tear it all apart and put some of the components inside the cluster and some of them behind it, but that's about the best option I can think of for it.

There was someone who'd managed to reverse engineer the cluster... so they could independently drive each of the needles and so on... can't for the life of me remember who that was though.... maybe someone on Racer's Edge if I recall correctly.

Doh, and that was a 2000-05 style of cluster... wouldn't help ya, if you're using the 96 cluster. Sorry...

Bought a Sunpro Tach II - Tach for now. Opened it up. It has (4) contacts to the Needle drive motor just like the Sunfire Tach. Was going to cut the contact pins off of the Sunfire Tach and wire in the Sunpro tach and attach it to the back of the IPC with it hooked up to the 3800SC as it is right now. Just can't figure out which of the (4) wires on the Sunpro backboard goes to SIN+, SIN-, COS+,COS- wires in the Sunfire IPC.

QuikLilCav and John Lenko. I've gotten lots of help from you guys over the past (2) years, and I've probably never said "Thank You" once. So... "Thank You" for all the help.

My Sunfire is running strong with the 3800SC. So strong that I have to keep it throttled down because it wheel hops in 1st and spins all the way through 2nd gear. It's a 5-speed (Isuzu rebuilt with '93 GEO Storm third member ass'y (machined gears) and Team Green LSD).

Again, "Thank You" to you guys, and anyone else that has helped me here at the "Body"... Steve Roberts

John ???

You're welcome. Glad to hear your car is kicking ass with the new drivetrain.

As far as your tach goes, I would suggest taking the two motors and putting them side by side on the table. Take something like a 9V battery and run the power to the opposing pins. I'm guessing that the motors are of the same design. If so, you should be able to run the wires in the same order. Sounds like it should work for you.
